TE Connectivity 2-227079-2 BNC Connector Plug Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-227079-2 is a BNC connector plug designed for 50-ohm coaxial cable applications. This male pin connector features crimp termination for both center contact and shield, with a bayonet lock fastening mechanism. The part is classified as Active and maintains 1064 units in current inventory stock.

Substitute parts become necessary when the primary part reaches end-of-life status, when alternative compliance certifications are required, or when specific cable group compatibility is needed for system integration. The parts listed below provide functional equivalence within defined electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 2-227079-2 is determined by the following core parameters: BNC connector style, male pin plug type, 50-ohm impedance, crimp termination for both center contact and shield, free-hanging in-line mounting, bayonet lock fastening, 4 GHz maximum frequency, 500 V voltage rating, 500 mating cycles, and 0.2 dB insertion loss.

Substitute parts are grouped into three categories based on their relationship to the main part:

Direct Manufacturer Equivalent (2-5227079-2): Identical electrical and mechanical specifications with differences in body material composition and RoHS compliance status.

Parametric Equivalents (2-5221128-3, 5225395-8, 9-331350-3): Parts meeting all core electrical parameters with variations in dielectric material, body material, or finish specifications that do not affect functional compatibility within the defined parameter set.

Similar Cross-Manufacturer Parts (112132, 112514): Amphenol RF alternatives meeting core BNC specifications with differences in cable group compatibility and contact termination options.

Cable group compatibility is not a substitution-limiting factor when the connector's electrical and mechanical parameters remain constant. Dielectric material variations (polyethylene, PTFE, or acetal) are acceptable within the specified frequency and voltage parameters.

Engineering Selection Recommendations

Primary Selection (Active Status): The TE Connectivity 5225395-8 is the recommended substitute when the main part 2-227079-2 is unavailable. Both parts maintain Active product status, meet all core electrical and mechanical parameters, and carry RoHS Compliant certification. The 5225395-8 uses PTFE dielectric material instead of polyethylene, which provides equivalent performance within the specified 4 GHz frequency and 500 V voltage parameters.

Alternative Selection (Active Status, Cross-Manufacturer): The Amphenol RF 112132 and 112514 are Active alternatives from a different manufacturer. Both parts meet all core BNC specifications and carry ROHS3 Compliant certification. The 112514 offers extended operating temperature range (-65°C ~ 165°C) compared to the main part (-55°C ~ 85°C), making it suitable for applications requiring broader thermal performance. The 112132 is compatible with a different cable group set (RG-174, 188, 188A, 316, LMR-100, M17/119-RG174) than the main part.

Compliance Consideration: If RoHS compliance is a system requirement, the main part 2-227079-2 (RoHS non-compliant) must be replaced with one of the RoHS Compliant or ROHS3 Compliant alternatives listed above.

Obsolete Part Avoidance: The parts 2-5227079-2 and 2-5221128-3 carry Obsolete status and should not be selected for new designs or long-term supply chain planning, despite meeting electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5225395-8 directly replace the 2-227079-2 in existing assemblies?

A: Yes. Both parts meet identical electrical specifications (50 ohms, 4 GHz maximum frequency, 500 V voltage rating, 0.2 dB insertion loss), use crimp termination for center contact and shield, feature bayonet lock fastening, and support 500 mating cycles. The dielectric material difference (PTFE versus polyethylene) does not affect functional compatibility within these parameters.

Q: What is the difference between the Amphenol RF 112132 and 112514?

A: Both are Active BNC male plug connectors with 50-ohm impedance and crimp termination. The 112514 supports both crimp and solder contact termination options, whereas the 112132 supports crimp only. The 112514 operates across a wider temperature range (-65°C ~ 165°C) compared to the 112132 (temperature range not specified). The 112514 is compatible with cable groups RG-55, 142, 223, 400, while the 112132 is compatible with RG-174, 188, 188A, 316, LMR-100, M17/119-RG174.

Q: Why is the main part 2-227079-2 listed as RoHS non-compliant?

A: RoHS compliance status is determined by material composition and manufacturing processes. The 2-227079-2 does not meet RoHS requirements, while equivalent parts such as 2-5227079-2, 2-5221128-3, 5225395-8, 112132, 112514, and 9-331350-3 do meet RoHS or ROHS3 compliance standards. System requirements may mandate selection of compliant alternatives.

Q: Are there packaging differences between substitute parts?

A: Yes. The main part 2-227079-2 is supplied in Bulk packaging. The 2-5227079-2 packaging is not specified. The 2-5221128-3 and 5225395-8 are supplied in Bulk. The 112132 and 112514 are supplied in Bag packaging. Packaging format does not affect electrical or mechanical compatibility but may impact procurement and inventory management processes.

Q: What does "Discontinued at DiGi Electronics" mean for the 9-331350-3?

A: This status indicates the part is no longer actively distributed through DiGi Electronics channels, though it may remain available through other sources. For new designs and long-term supply chain planning, selection of Active status parts (5225395-8, 112132, 112514) is recommended.

Q: Can the 112514 be used in applications requiring solder termination instead of crimp?

A: Yes. The 112514 supports both crimp and solder contact termination options, providing flexibility for different assembly processes. The main part 2-227079-2 and most other listed substitutes support crimp termination only.

Q: How do I determine which substitute is appropriate for my application?

A: Verify that the substitute part meets your system requirements for: connector style (BNC), connector type (male plug), impedance (50 ohms), termination method (crimp or solder), operating temperature range, RoHS compliance status, and cable group compatibility. All listed substitutes meet the core electrical parameters of the main part.
